I am working with Apple Wallet Pass and want to include a unique ID in each instance of the pass so that I can easily enforce one-time usage, as in the case of an event ticket. I do not care whether this be the serialNumber, barcode, etc.. Are there any such wallet pass fields that can be changed without needing a new signature for the pass?
If I am distributing 100,000 tickets for an event in the form of Apple Wallet passes, does each individual pass really need to be signed independently? This perhaps strikes me as excessive? But I can’t see how else you could determine if, say, ticket 900 has already been used? (i.e. each wallet pass ticket has to have a unique ticket number in it, necessitating a unique signature)
